In an important step in India’s formidable programme to raise its astronauts into house, the Indian Space Research Organisation (ISRO) will check its crew escape system (CES) on October 21, 2023. The flight, from Sriharikota, will check if the CES can defend the astronauts ought to the launch car malfunction. ISRO has designated this mission TV-D1.
According to an ISRO assertion, the check will start between 7 a.m. and 9 a.m. When the launch car – match with the crew module and the CES – reaches a velocity of 1.2 Mach and an altitude of 17 km, an abort command might be issued. The module with the CES will separate from the rocket and deploy a collection of parachutes, and finally splash down within the Bay of Bengal, the place Navy personnel will get well it. The entire sequence might be uncrewed.
In the last word mission that can hoist the astronauts right into a low-earth orbit in 2024 or 2025, the rocket would be the Launch Vehicle Mark-3 (LVM-3). But that on October 21 might be a single-stage rocket powered by liquid propellants. It was purpose-built for the TV-D1 mission and wheeled to the launch pad on October 15.
ISRO Chairman S. Somanath spoke to T.S. Subramanian for The Hindu about this check, the crew module, and preparations for the human spaceflight programme, a.okay.a. ‘Gaganyaan‘. Excerpts from the interview follow:
You will be soon testing the crew escape system of the Gaganyaan project, which will ultimately take the Indian astronauts into space. Have you made the LVM-3 rocket more powerful to carry the big crew module?
Gaganyaan has many, many elements [and] components. The rocket is one part of it. The rocket LVM-3, which will take the crew to orbit, is being strengthened. The process of strengthening it is already completed. That is called the ‘human rating’ of the car. It is already over. All methods and engines have been examined and confirmed. So our rocket – human-rated – is nearly accomplished.
There is one other factor known as the crew module and the crew escape system. The new crew module is underneath improvement. It is being examined. There is not any functionality in India to manufacture it. We have to get it from outside. That work is at the moment going on.
We wished quite a bit of know-how to come from outside, from Russia, Europe, and America. But many didn’t come. We solely received some gadgets. That goes to take time. So we have now to develop methods resembling environmental management and life assist methods. We name it ‘ECLSS’. That has to be developed internally. We have developed its engineering mannequin. This is principally for controlling the temperature, oxygen, wastage course of, vibration, hearth hazards, and so many [other] issues.

We have to make a crew escape system. That is, within the case of any harm to the rocket, the crew will [have to] be taken away from the rocket and saved.
Finally, there’s a system known as Integrated Vehicle Health Management System, or IVHMS, which has intelligence. It will sense an imminent failure and take abort motion. It will autonomously resolve. This system is underneath improvement. These are new issues. We have to check all of them over a interval of time.
Hundreds of tests are deliberate: helicopter-based tests, test-vehicle-based tests, rocket-based tests, abort tests, unmanned [tests], robotic missions, and so on. All these might be executed. For the subsequent one 12 months to a 12 months and a half, this might be our programme. Every day, there’s some check occurring. Every subsystem and element goes via tons of of tests. When a serious check occurs, the press will learn about it.
The check car check will occur in October [i.e. October 21]. It might be an abort check. The launch car will take the unmanned crew module up to a top of 17 km. Then we are going to say the mission is ‘aborted’. It will [have to] be saved utilizing the crew escape system. It will carry again the module to the ocean and we are going to accumulate it.
In the actual mission, will three Indian astronauts go within the crew module to low-earth orbit?
Finally how many individuals will go, we are going to resolve later. Not now. We don’t have to ship three… We may also ship one within the first mission. There is not any hurry to ship three. We can ship one after the other. Ultimately, we will ship even 10 astronauts. Why restrict to three? That will not be a measure of something. If you’re able to ship a human being into house, that’s it.
It relies upon on our confidence at that time of time… Only once we are very positive of ourselves, we are going to ship human beings into house. Otherwise, we won’t do this. In my opinion, it’s going to take extra time than we actually thought of. We will not be fearful about it. What we’re fearful about is that we must always do it proper the primary time.
The schedule is secondary right here. Even if I ship an individual tomorrow, I’m not going to obtain something apart from declare that I’ve despatched this individual. The functionality improvement is most necessary. Technology improvement is most necessary. Some claims I made final 12 months will not be necessary. I’m focusing on functionality improvement.
